Converting to flac
« on: March 04, 2012, 07:51:29 am »

When I convert wav to flac i use the level 8 which is the one that compress most.
Sometimes when I play my music there occurs a quite gap in a song. It is very short. Maybe a half-one second.
But it is annoying anyway. Can the compress grade affect on that?

I have a pretty decent i3 pc which I use for film and music only.

I have already laborated with the output settings. I use wasapi and neither upsampling or downsampling.

Thanks in advance...

You can easily check if flac compression has anything to with it by looking at cpu usuage during play. You can check the 'play files from memory' on the Audio settings as well.
Flac compression is a sort of legacy where cpu cycles and harddisk space were scarce and isn't realy an issue any more.
I have been using compression '6' all the time since mediajukebox 8.

Did you try wasapi event style ?

Yes, I have tryed Wasapi Event style. That was worse than the normal Wasapi.
What is the different between them anyway?
Tha gaps are shorter than a half second as I stated before. It just happend, And I noticed it is shorter.
But when listen music sometimes it appears longer  :(

I have all the time used compression 8. Maybe I should go down to 6? It is not a bis step but still.
It is the MC default.
Should not be any problem to change, right? I just need to mark the whole library and then convert
in tools.

Have a look at http://wiki.jriver.com/index.php/WASAPI
Maybe the explanation for your hiccups is in here.

If you want to try the compression factor, do it in a limited scale to see if it makes any difference.

FLAC compression level is about the amount of ‘time’ FLAC is allowed to use to find the best possible compression. This is obvious about creating a FLAC file.
As far as I know the impact on decoding (playback) is minimal.

You can convert a FLAC to WAV and check if this makes any difference at all.
You can run the DPC Latency checker to inspect overall system latency.
If this is to high you will experience a drop out now and then

Hi Vincent
That I will do. I didn´t know about this software.

And you mbagge, thanks for the link. That will be useful. I think I will try event style again. According to the
link that should be better than just plain Wasapi.
